Almost as amazing as magic, as it would be. The US gallon is smaller, so less miles per gallon (29 or thereabouts). You have the correct ratio, but upside down (you would need to divide by 1.2 rather than multiply).

The difference is confusing, as there are four Imperial quarts (and 8 Imperial pints) per gallon. The Pint, however, is defined as 20 oz. in Imperial measure, not 16 oz as in US measure (for reasons I probably don't want to know!). A pint in an English Pub is 20 oz, in the US it will be 16. The result is that the US gallon is somewhat smaller, as are our pints and quarts. Imperial quarts are larger than a liter, US quarts are smaller.
